Abstract

High-entropy materials (HEMs) demonstrate great potential in electrochemical energy storage systems owing to their diverse elemental compositions and tunable physicochemical properties. In lithium‑sulfur (Li–S) batteries, the synergistic effects among the multiple components of HEMs can enhance the conductivity of electrode materials, strengthen the chemisorption of lithium polysulfides (LiPSs), and catalytically accelerate their reaction kinetics, ultimately improving energy density and cycle life. In this review, the definition and fundamental characteristics of HEMs are introduced; the advantages of HEMs in Li–S batteries applications are systematically analyzed. Followed by the design strategies for using various HEMs as sulfur hosts, separator modifiers, interlayers, and solid electrolytes to enhance the performance of Li–S batteries are comprehensively reviewed. Finally, the remaining challenges and future research directions for integrating HEMs into Li–S batteries are discussed. This review aims to offer valuable insights into the development of HEMs in advanced Li–S batteries.

用于先进锂硫电池的高熵多硫化物调节材料

高熵材料由于其不同的元素组成和可调的物理化学性质，在电化学储能系统中显示出巨大的潜力。在锂硫（li -硫）电池中，HEMs多组分之间的协同效应可以增强电极材料的导电性，加强多硫化锂（LiPSs）的化学吸附，并催化加速其反应动力学，最终提高能量密度和循环寿命。本文简要介绍了hem的定义和基本特征；系统分析了HEMs在锂硫电池中的应用优势。其次，综述了利用各种hem作为硫载体、分离器改性剂、中间层和固体电解质来提高锂- s电池性能的设计策略。最后，讨论了将HEMs集成到Li-S电池中所面临的挑战和未来的研究方向。本综述旨在为先进锂硫电池中HEMs的发展提供有价值的见解。

期刊介绍： The Chemical Engineering Journal is an international research journal that invites contributions of original and novel fundamental research. It aims to provide an international platform for presenting original fundamental research, interpretative reviews, and discussions on new developments in chemical engineering. The journal welcomes papers that describe novel theory and its practical application, as well as those that demonstrate the transfer of techniques from other disciplines. It also welcomes reports on carefully conducted experimental work that is soundly interpreted. The main focus of the journal is on original and rigorous research results that have broad significance. The Catalysis section within the Chemical Engineering Journal focuses specifically on Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis. These studies have industrial impact on various sectors such as chemicals, energy, materials, foods, healthcare, and environmental protection.
